SUPPORT FOR TELEPHONE APPARATUS.

SPEGIFIGATION forming part of Letters Patent No. 681,812, datedSeptember 3, 1901.

Application filed September 19, 1898. Serial No. 691,389. (No model.)

To all whom, it may concern:

Be it known that I, ELIAS E. RIES, a citizen of the United States, and aresident of New York, in the county and State of New York, have inventedcertain new and useful Improvements in Supports for Telephone Apparatus,of which the following is a specification.

My invention relates to supports for telephone instrumenis,and moreespecially to the mounting of telephone-transmitters designed for use ondesks and other places where the subscriber using the same is so seatedor located with reference to the instrument that either aninconveniently-projecting stationary telephone apparatus or an equallyobj ectionable portable transmitter outfit has heretofore been necessaryin order to bring the mouthpiece of the transmitter within properoperative proximity to the subscriber or user during conversation.

The objects of my invention are to obviate the necessity for suchobjectionable stationary instruments and for portable telephoneinstruments of the type heretofore known as desk sets, which latter havebeen found to be open to the objection that they are frequently in theway of books, papers, &c., lying about on the desk or table upon whichthe instrument is to be used, as well as to provide a neat, compact,convenient, and attractive transmitter outfit for desk and other usethat is free from the objections just cited and which possesses otherincidental advantages.

These objects I accomplish by supporting the transmitter proper upon anextensible tube or other support interposed between said transmitterorits mouthpiece and the stationary base-board or box containing theremaining portions of the transmitting outfit in such a manner that themouthpiece or its support may be pushed back out of the way when not inuse and that it may be readily extended or moved toward the lips when itis desired to converse over the line, particularly at such times when itis desirable for privacy or other reasons to speak in a low tone orvoice.

In carrying out my invention I mount the transmitter diaphragm, togetherwith its mouthpiece, at the forward end of said ex tensible support andutilize said support as a duct for one or more flexible wires that aredesigned to carry the currents produced in the transmitter-circuit whenthe apparatus is in use.

Figure 1 is a side elevation, extended, of one form of myinvention inwhich the mouthpiece and the transmitter proper are mounted togetherupon the outer end of the extensible supporting arm or tube. Fig. 2 is alongitudinal section of the tubular support illustrated in Fig. 1 as itappears when closed. Fig. 3 is a longitudinal section of a three-sectiontelescopic transmitter-support, showing the transmitter conducting-cordslying within the same.

Referring to the drawings, a is a base board or support, which may bethe front of a box A, containing the induction-coil, callbell, andotheraccessory telephone apparatus that is fastened to a suitablesupport--as, for example, the inside back of a roll-top desk. The frontof the base a is reinforced by a suitable socket a. The transmitter 13and its mouthpiece B are mounted together upon the end of the innertube-section. In Figs. 1 and 2 the extensible support consists of twotubeseotions G and O, which latter serve as the electrical conductorsleading from one terminal of the microphone to the binding-post l) ofthe transmitter-circuit. The other terminal of the microphone isconnected by a flexible conducting spring or wire 1), extending throughthe tube to the binding-post b" of this circuit. To prevent unduetwisting of the conducting-spring b,the inner tube 0" may be grooved orslotted, as shown at s of Fig. 2, said groove or slot being engaged by astop screw 3 in the outer tube 0. The base or socket a is in this casepreferably made in the form of a flanged sleeve, which is brazed orotherwise secured to the outer tube C at or near its rear end. In Fig. 3I have shown an extensible support, also made of three telescopicsections, the transmitterconductors being shown in the form of anordinary conducting-cord containing a pair of insulated twistedconductors, the transmitter being in this instance insulated from thetube proper by a rearward projection of insulation which extends intothe last section of the tube and through which the terminals of thetransmitter pass.

Having thus described my invention, what lated conductors extending fromsaid terminals through the telescopic tube to the apparatus at the boxor base-board, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two Witnesses, this 8th day of September, 1898.

ELIAS E. RIES.
